A WHOIS check tells you if one TLD is taken. Domain GPT runs your name across 1,147 TLDs in parallel, surfaces premium aftermarket listings, and generates 100 brandable alternatives — all in one query.
We query authoritative registry endpoints in real time and cache results only for a few seconds. If a domain shows as available here, you can register it in the next click.
We aggregate listings from Sedo, Afternic, Dan, GoDaddy Auctions and several niche marketplaces. Pricing reflects the seller's asking price; we never mark up.
A custom model trained on brand naming patterns rewrites your seed word using prefixes, suffixes, blends and phonetic variants — then filters to short, sayable, register-able names.

Yes — we ship a public REST API and a typed JS SDK. The free tier covers 5,000 lookups per month; paid tiers scale to millions with a 99.95% SLA.
